Professional Electric Fault Finding and Repairs by Juspropa
Electrical faults can occur without warning, causing power outages, tripping circuit breakers, flickering lights, damaged appliances, and serious safety hazards. Whether you’re experiencing recurring electrical problems in your home, office, or commercial property, professional electrical fault finding and repairs help identify the root cause and restore your electrical system safely and efficiently.
At Juspropa, our qualified in-house electricians specialise in diagnosing and repairing electrical faults in accordance with SANS 10142-1 standards, ensuring your electrical installation remains safe, compliant, and reliable.
What Is Electrical Fault Finding?
Electrical fault finding is the systematic process of identifying, diagnosing, and resolving problems within an electrical installation. Rather than simply treating the symptoms, fault finding aims to determine the exact cause of an electrical issue to prevent recurring failures and potential hazards.
Electrical faults can affect:
- Residential homes
- Apartments and complexes
- Commercial buildings
- Industrial facilities
- Retail stores
- Offices and warehouses
Professional fault finding combines technical expertise, specialised testing equipment, and methodical troubleshooting techniques to locate hidden electrical problems.
Common Types of Electrical Faults
Short Circuits
A short circuit occurs when live conductors come into direct contact with neutral or earth conductors, creating excessive current flow. This often causes circuit breakers to trip immediately.
Common causes include:
- Damaged insulation
- Faulty appliances
- Incorrect wiring connections
- Rodent damage to cables
- Water ingress into electrical systems
Earth Leakage Faults
Earth leakage occurs when electricity unintentionally flows to earth rather than through its intended circuit path.
Common signs include:
- Earth leakage units tripping repeatedly
- Electrical shocks from appliances
- Intermittent power outages
Overloaded Circuits
Electrical circuits become overloaded when too many appliances draw power from the same circuit.
Warning signs include:
- Frequent breaker trips
- Warm plug sockets
- Dimming lights when appliances operate
- Burning smells from outlets
Open Circuit Faults
Open circuits occur when there is a break in the electrical pathway.
Causes include:
- Broken conductors
- Loose connections
- Failed switches
- Damaged circuit breakers
Intermittent Electrical Faults
These are faults that appear and disappear unpredictably, making them particularly difficult to diagnose.
They may result from:
- Loose connections
- Moisture penetration
- Thermal expansion of components
- Failing electrical equipment
Signs You Need Electrical Fault Finding Services
Contact a qualified electrician if you notice:
- Circuit breakers tripping repeatedly
- Earth leakage switch constantly switching off
- Partial or complete power loss
- Flickering or dimming lights
- Burning smells near electrical installations
- Buzzing sounds from switches or DB boards
- Electrical shocks when touching appliances
- Hot plug sockets or switches
- Appliances repeatedly failing
- Sudden increases in electricity consumption
Ignoring these warning signs can increase the risk of electrical fires, equipment damage, and personal injury.
When Do You Need Electrical Fault Finding?
After Repeated Power Trips
If your circuit breakers continue to trip after being reset, there is likely an underlying fault that requires professional diagnosis.
Before Purchasing a Property
Fault finding inspections can identify hidden electrical defects before buying a home or commercial building.
If required, our Electrical Certificate of Compliance (CoC) services can help verify whether the installation complies with safety regulations: https://www.juspropa.com/za/shop/product/electrical-certificate-of-compliance-coc/
Following Renovations or Alterations
Electrical modifications may introduce faults if not installed correctly.
When Appliances Are Damaged
Frequent appliance failures may indicate voltage fluctuations, earth faults, or wiring problems.
During Preventative Maintenance
Routine inspections help identify issues before they develop into major failures.

How Is Electrical Fault Finding Done?
Professional fault finding follows a structured diagnostic process.
1. Gathering Information
The electrician collects information about:
- When the fault occurs
- Which circuits are affected
- Previous repair history
- Recent electrical changes
- Symptoms experienced
Understanding the history of the problem helps narrow down possible causes.
2. Visual Inspection
A detailed inspection is carried out to identify visible issues such as:
- Damaged wiring
- Burn marks
- Loose connections
- Corrosion
- Water damage
- Overheated components
3. Isolation of Circuits
Circuits are systematically isolated to determine which area of the installation contains the fault.
This process reduces unnecessary disruption while improving diagnostic accuracy.
4. Electrical Testing
Specialised instruments are used to test the installation.
Common tests include:
- Continuity testing
- Insulation resistance testing
- Earth continuity testing
- Polarity testing
- Earth loop impedance testing
- Voltage measurements
- Load testing
5. Identifying the Root Cause
Once testing is complete, the electrician determines the exact source of the problem.
6. Carrying Out Repairs
Faulty components are repaired or replaced.
7. Verification and Retesting
Following repairs, the installation is retested to confirm that the fault has been successfully resolved.
Methods Used in Electrical Fault Finding
Professional electricians use several fault-finding techniques.
Divide and Conquer Method
Circuits are divided into sections and tested individually until the fault is isolated.
Elimination Method
Potential causes are systematically ruled out until the source is identified.
Dead Testing
Testing performed while the electrical system is isolated from power.
Examples include:
- Continuity testing
- Insulation resistance testing
Live Testing
Testing conducted while circuits are energised.
Examples include:
- Voltage measurements
- Load analysis
- Current testing
Thermal Imaging
Infrared cameras identify hotspots caused by:
- Loose connections
- Overloaded circuits
- Overheating components
Clamp Meter Analysis
Current flow is measured without disconnecting conductors.
How Are Electrical Faults Fixed?
Repair methods depend on the nature of the fault.
Common solutions include:
- Replacing damaged wiring
- Tightening loose connections
- Replacing faulty circuit breakers
- Repairing earth leakage faults
- Replacing damaged plug sockets and switches
- Redistributing overloaded circuits
- Upgrading outdated DB boards
- Replacing defective electrical components

Can You Clear Electrical Faults Yourself?
Simple actions may help identify obvious issues:
- Unplug recently connected appliances
- Reset circuit breakers once
- Check whether neighbours are experiencing outages
- Switch off damaged appliances
However, avoid attempting repairs involving:
- Exposed wiring
- DB boards
- Circuit breakers
- Earth leakage devices
Electrical fault diagnosis and repairs should always be performed by qualified electricians to avoid injury and property damage.
Future-Proofing Your Electrical Installation
Preventative measures can reduce future faults.
Schedule Regular Electrical Inspections
Routine inspections identify problems before failures occur.
